             Summary: new producer performance and bug improvements
                 Key: KAFKA-1498
                 URL: https://issues.apache.org/jira/browse/KAFKA-1498
             Project: Kafka
          Issue Type: Bug
          Components: core
            Reporter: Jun Rao
            Assignee: Guozhang Wang


We have seen the following issues with the new producer.

1. The producer request can be significantly larger than the configured batch size.
2. The bottleneck in mirrormaker when there are keyed messages and compression is turned on.
3. The selector is woken up on every message in the new producer.
